Jenn-Air gas cooktop igniters work for most of the life of the appliance without you ever having to think about them. They light reliably and automatically relight when the burner's flame is accidentally extinguished. However, as igniters do most of the cooktop's work, they are the most common point of failure. Jenn-Air gas cooktop igniters are designed to be easy to replace. But Jenn-Air recommends that consumers call a technician for replacement. Home repairs will not be covered under your gas cooktop's warranty.

Step 2

Unplug the cooktop.

Step 3

Lift off the burner grate.

Step 4

Lift off the burner cap.


Step 5

Remove the two screws that hold the burner base in place. Lift the burner base off of the cooktop to reveal the igniter assembly in the center of the burner.

Step 6

Repeat Steps 3 through 5 with the other burner housed on the same side of the cooktop. Most Jenn-Air cooktop covers are in two to three sections. If your cooktop cover is all one piece, you will have to remove all four or five burner assemblies before lifting the cooktop cover.


Step 7

Lift the cooktop cover.

Step 8

Follow the igniter cable back to the ignition control module at the back of the cooktop.

Step 9

Unscrew and remove the cover on the ignition control module.


Step 10

Unplug the igniter cables. Lift the igniter assembly off of the cooktop.

Step 11

Install the new igniter assembly in the opposite manner. Plug the ceramic wires in first, then place the igniter assembly in place.

Step 12

Replace the igniter assembly's cover and its screws. Replace the cooktop cover. Replace the burner bases and screws. Replace the burner caps. Replace the burner grates.

Step 13

Plug the cooktop back in and reopen the gas line.
